WALTHAM – Boston Celtics president of basketball operations Danny Ainge confirmed Friday that two of Doc Rivers' assistant coaches will remain with the team to serve on new coach Brad Stevens' staff.

Jay Larranaga and Jamie Young should help Stevens transition to the NBA, but Ainge said the rest of the staff hasn't entirely taken form.

Larranaga, Young and former Toronto Raptors coach Alvin Williams are all in Orlando, Fla., helping coach the Celtics' summer-league entry. So is Kwame Graves-Fulgham, a former Amherst Regional High School star who played at Brandeis University and serves as the Celtics' video coordinator. Ainge didn't seem positive, but he also indicated that he believes former Milwaukee Bucks assistant Joe Wolf is helping with the summer-league entry.

Further discussing the Boston staff, Ainge said he would help Stevens piece it together "as much as he wants my help."

"We've talked about it a lot over the last couple of days, of staffing, and we're looking into that," Ainge said. "He has some ideas of guys ... Really we only have two holdover coaches in Jay Larranga and Jamie Young who will stay, which he wants. Those aren't because they were just here. They're people he wants."

Ainge said he isn't overly worried about adding more established assistant coaches, citing the experience of Young and Larranaga.

"Yeah, he'll probably get another one – another NBA-experienced guy," Ainge said. "But Brad's a quick learner. I'm not so worried about him learning the NBA game."

One person who could be considered is Drew Cannon, who served as Butler's statistical guru.

"I haven't talked to Drew yet," Ainge said. "I know Brad is very fond of him and I'm not sure where that's going to lead."

Stevens said he's likely to look for coaches who hold expertise in areas that aren't his strong suits.
